Fully hydraulically-controlled roll-bending machine with 3 driving rolls and double pre-bending. The side rolls traverse and are fitted with a planetary movement to facilitate pre-bending on both edges of the sheet metal.

They are driven by four hydraulic cylinders, two per each roll, to ensure high pressure during bending. Rotation is by means of a hydraulic motor coupled with an epicyclic reduction gear and a clutch-operated torque limiting device situated on the upper roll to adjust any variation in the peripheral speed be- tween the roll and sheet metal. Parallelism between the two side rolls is by means of a simple system to ensure easy correction and adjustment of inclination. The release device is opened by means of a hydraulic cylinder which is controlled directly via a selector switch on the control panel. The machine is supplied complete with all safety devices as prescribed by current laws.
